Bathroom Resealing in Great Wymondley
Bathroom resealing across Great Wymondley and nearby, with every bit of old sealant taken out first.
- Splits where the tray meets the wall
- Water getting behind the bath panel
- Failed sealant on the screen profile
Different surfaces, different methods
Sinks & splashbacks
Next to the sink, the sealant has to cope with constant water, and a food-safe product where it’s needed. The joint is laid neatly so it’s easy to wipe.
Kitchen worktops & upstands
Water behind a laminate worktop can make the edge swell. A sound joint along the back edge stops that.
Bathroom resealing for homes and businesses in Great Wymondley
A shower joint gets soaked every day. Tray edges, screen profiles and wet room joints all rely on silicone to stay watertight. They’re resealed with anti-fungal sanitary silicone, finished smooth so water drains away rather than collecting. We’re often asked to deal with a reseal done over the top of the old bead and lumpy, uneven sealant from a DIY attempt, on basins & vanity units, sinks & splashbacks and kitchen worktops & upstands.
In a village or hamlet like Great Wymondley, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
There’s a 12-month guarantee on every job, large or small.

Bathroom resealing around Great Wymondley
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in. Great Wymondley has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Rented homes near Hitchin station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. For an older house near a landmark such as Church of St Mary the Virgin, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Why it’s worth doing now in Great Wymondley
Sorting it now is quick: it takes two to three hours for a typical bath, depending on how much old sealant there is. Wait for a leak and you may be looking at panels off, drying out and redecorating too. Where a wall is exposed, as many are in small places like Great Wymondley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

What we’re called out for in Great Wymondley
With age, silicone loses its stretch. In kitchens it often shrinks away from the back edge, opening a hairline gap that lets water and crumbs in. Hot pans and harsh cleaners don’t help.
Signs it’s time to call us include:
- Leaks into the floor or ceiling below
- Mouldy sealant that has gone black
- Sealant that has split, shrunk or peeled away
- Two layers of silicone, both failing
For site and facilities teams at buildings such as Wymondley Junior Mixed and Infant School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
Questions to ask before booking
- What product goes in the joint
- How the surfaces are prepared before sealing
- Are they insured?
- Who turns up on the day
How the visit works
There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes two to three hours for a typical bath, depending on how much old sealant there is from start to finish. Somewhere as small as Great Wymondley, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- The joint is cleaned, degreased and treated for mould.
- The joint is left to dry, and baths are filled with water first.
- We apply anti-fungal sanitary silicone in one even bead and tool it neatly.
- Finally we tidy up and explain the cure time before we leave.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
- Let us know about stairs, lifts or work at height

Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you guarantee your resealing?
Yes. Every job carries our one-year guarantee, and we’re fully insured.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
